More or Less: Behind the Stats - Why is Kenya?s election so expensive?

On Tuesday Kenyans go to the polls to elect members of parliament and the next president. A report in Quartz Africa has estimated that the cost of putting on the election by the Government works out at around $25 per head ? $480 million in total.

More or Less: Behind the Stats - Calling the shots at Wimbledon

Using statistics to prove or disprove the wisdom of tennis is the theme this week. In this digital age we are used to information at our fingertips. This week More or Less finds out how every rally, every shot at this tennis championship is counted and makes its way to our phones, desktops and TV screens. And once you have this information ? what can you do with it? Is it useful for players and coaches? Traditionally, players will take a risk on their first chance to serve, and hit the ball as fast as they can, knowing that they have a second chance. On their second attempt, players tend to serve more slowly and carefully to make sure it goes in. But could the statistics show they might as well take a risk again?

Start the Week - From Darwin to Big Data with Richard Dawkins

On Start the Week Andrew Marr asks whether scientists have failed in their task to communicate their work to the wider public. The 'passionate rationalist' Richard Dawkins has spent his career trying to illuminate the wonders of nature and challenge what he calls faulty logic. But he wonders whether Darwin would consider his legacy now with 'a mixture of exhilaration and exasperation'. The child psychologist Deborah Kelemen has been working with young children to find out what they make of adaptation and evolution with the storybook, How the Piloses Evolved Skinny Noses, and is encouraged by the sophistication of their understanding. The mathematician Cathy O'Neil says it's time people became more aware of the mathematical models and algorithms that dominate everything we do online and in finance, and yet are increasingly opaque, unregulated and left unchallenged. While Alex Bellos looks to improve numeracy with puzzles and brainteasers which have been entertaining and frustrating people for centuries. Producer: Katy Hickman.
